Pressure Reducing and Sustaining Valve IR-423-55-KX

The BERMAD Model IR-423-55-KX is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and reduces downstream pressure to a constant preset maximum. It either opens or shuts in response to an electric signal.

  • Line Pressure Driven, Electrically Controlled On/Off

-Protects downstream system

-Prioritizes pressure zones

-Controls system fill-up

-Sustains upstream line pressure

  • Advanced Globe Hydro-Efficient Design

-Unobstructed flow path

-Single moving part

-High flow capacity

  • Fully Supported & Balanced Diaphragm

-Requires low actuation pressure

-Excellent low flow regulation performance

-Progressively restrains valve closing

-Prevents diaphragm distortion

  • User-Friendly Design

-Easy pressure setting

-Simple in-line inspection and service

Typical Applications

  • Computerized Irrigation Systems
  • Line Fill-Up Control Solutions
  • Pressure Reducing Systems
  • Remote and/or Elevated Plots
  • Infield Filter Backwash Pressure Sustaining
  • Systems Subject to Varying Supply Pressure
  • Distribution Centers
